The dermatologist has long been aware that persistent and prolonged traction of the hair of the scalp may produce baldness. Many of the more recent writings devoted to the care of the scalp and hair of the female explicitly warn of the necessity of avoiding prolonged traction on any portion of the scalp. Repeated pulling of the hair has been shown to cause inflammation, with its resultant consequences.
In spite of the repeated admonitions, the pony tail in recent years has enjoyed unusual fascination and popularity among our younger females. It is clear that those who wear the pony tail longer and more tightly drawn are considered more accomplished in the eyes of their contemporaries. It is the prolonged pulling of the hair backward and upward into a smoothly compacted corded hair bundle that has caused loss of hair in many of these persons.
